VAPORIZING DEVICE FOR EXPLOSIVE-ENGINES.

Specification 01' Letters Patent.

Patented Aug. 115, 19123.

"To all whom it mag concern Be it known that we, Armor Low and "'I'IARRY' Hnutrznnnc, citizens of the United States, and residents, respectively, of-Horscshoe, county of St. Lawrence, and State of New Yorle'and of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Vaporizin'g Devices :t'or Explosive-Engines, of

which the following is a specification.

This invention relates to explosive en .ginesand has for its object the provision of .a s'imple and efiicient device for vaporizing 15 the fluid to form the explosive charge.

' The device shownin the accompanying drawings and Whichwill he described here-- inafter is'particularly adapted for engines of the type using kerosene oil. In engines ofthis type a common means of vaporizing the oil hasbeen to cause the same to be delivered inastream or spray against a hot plate in the-cylinder head, thus causing the same to vaporize and mix with the proper amount of air to form the explosive mix ture.

My invention comprises a device, suhstantially in the form out a wire mesh or screen, which. is heated by suitable means and through which the liquid oil is caused to pass. By reason of the peculiar construe tion'arelatively large surface is provided against which the liquid oil will contact in P passing through the screen and is more quickly and thoroughly vaporized, thusprodu'cing inorcsatistectory and etlicient resuits. I

In the drawings accompanying this specification is shown. a simple embodiment of .IllYlIlVQIltlOlltlS adapted to he used in connection'with a kerosene engine.

in the several views of the drawings like parts have been given the same reference numerals.

Figure 1. is a. side elevation of a portion of an engine such as described. Fig. 2 is an enlarged seciioi'ial elevation of a portion of said engine. Fig. 3 a detail view of the vaporizing device. spcctive view showin f a. rmaliti atimi of the vaporizing device.

A portion of an engine cylinder is shown at 1.. At the upper end of this cylinder is a Villi'Q-Cllttl'lllQQI' in which is positioned the usual adn'liss'on valve controlling the admisginc cylinder through the valve chamber 3.

This mixing chamber is shown in Fig. :2 in section.

The vaporizing device as shown in Fig. 3 in detail is also shown in section positioned in the mixing chamber in Fig. This device consists of a frame, pretcrablycf insulating material, such as shown at 5. Mounted in this't'ranie are a. series of conductors, such as 5, running from side to side oi said frame in parallel lines and provided with suitable wire connections 7 through which connection is made to a source ot cmrcnt. These conductors are of such size and material that the current passing therethrough will heat the same to the required amount and in which the amount of heating may be regulated hy the amount of.

current passing thcrellu'migh. Several il'ramcs or sets of conductors may be super; imposed upon each other; as shown in Fig. 2. The condi'lctors or wires in each frame are so arranged that the wires of adjacent frames run transversely to each other while the wires oi alternate 'l'ralucs run intermediary ot each other. W'hen placed together the wires of the several Frames are connected together in series with one an other and provide a mesh or screen which ma y be electrically heated from a suitable source of current. The appearance of this screen when formed as ahove'described by superimposing several sets of-conductius one upon another is shown in Fig. 3. It will he noted that this constructirm provides a relatively large contact surface for any fluid passing through the screen.

A modification of the frame for the wire mesh is shown in Fi 4. In this construction a single frame 5 takes the place of the several individual frames 5 in the construction just described. The several sets of wires are mounted in this frame 5 so as to be relatively positioned as described for the superimposed frames shown in Fig. 2 and also in Fig. 3.

The operation of the engine is as follows: The oil is forced through the mixing chamber from the supply pipe 8 and striking against the wires 6 of the screen which are heated electrically, is vaporized. This operation occurs duringthe upward stroke oi l'hepiston and the "aporized oil is carried ilirough the screen to the left as shown in Fig. 2. "Upon the return stroke of the piston the oil vapor is again drawn tlirougli the screen and mixes with the-air which is the same time drawn in from the supply pipe 9. This forms the explosive mixture which is then drawn into the cylinder 1 through the admission-valve.

It will lie-seen that by means of this consl'ruction the entering stream of oil is broken up and scattered by the wire mesh and is quickly vaporized by" reason of the large heating surface presented. by the screen. '1 iis not only results in a quicker vaporiza- Lion of the oil but the action is much more" thorough and produces a much more efli cient explosive mixture. i

The advantages obtained by the simple and compactconstruotion b means of which the necessity of heating iiliemva'porizer. arti ficially by outside means, such a gaso lene torch, ete, are avoided, will be obvious. As many changes could be made in the above construction and many apparently widely different embodiments of my invention designed Without departing from the scope thereof, We intend that all matter conthe accompanying drawings shall be interre'ted as illustrative merely of anoperative embodiment of our invention and not in a limiting sense.

ll hat We claim is: L In combination with an. explosive englee, a mixing chamber provided with fluid ndnnmnin means and an outlet to the en gine cylinder located adjacent one and there of and an air inlet intermediary of the ends thereof, and a vaporizer comprising a'screen positioned in the mixing chamber intermediary of the air inlet and the end of the chamber opposiie the fluid admission and the outlet to the engine cylinder, whereby the fluid is first forced through the screen and partially vaporized. and then repassed throngh the screen in iihe opposite direction, then mixed viith the air and drawn intothe I engine cylinden and means for heating said I screen. v

In combination with an explosive eng1ne, a, mixing chamber provided with fluid Kings and State of- Nefw'York, this 12th day of May, 1908. v
